Failing pip_install('scikit-image') on Slicer 4.13.0-2021-09-26 due to missing python-real.exe

This worked just fine for me previously on the stable version. This is the initial error message I get:

error: Application does NOT exists [C:/Users/mikeb/AppData/Local/NA-MIC/Slicer 4.13.0-2021-09-26/bin/./python-real.exe]

Followed by

There is, in fact, no python-real.exe in the referenced folder. Should there be?

pip_install('scikit-image') works for me on Windows with 4.13.0-2021-09-27, and python-real.exe exists on my computer here: c:\Users\andra\AppData\Local\NA-MIC\Slicer 4.13.0-2021-09-27\bin\python-real.exe.

The most likely culprit for a missing executable is a hyper-active antivirus software. Check your quarantined files. Not using third-party antivirus software or disabling automatic file delete/quarantine on the Slicer install folder and then reinstalling Slicer should fix the problem.

Thank you!! The problem was that Avast antivirus had quarantined the executable. I’m confused why it didn’t tell me about it though. I would have had a hard time figuring this out on my own.
